 This routine initializes a **qrm_spmat** type data structure from a **sparseMatrixCSC**.
 
 #### Input Arguments :
 
+In the first form,
+
 * `spmat`: the **qrm_spmat** sparse matrix to be initialized.
 * `A` : a Julia sparse matrix stored in **SparseMatrixCSC** format.
 * `sym` : a boolean to specify if the matrix is symmetric / hermitian (true) or unsymmetric (false).
+
+In the second form, the matrix `A` is specified using
+
+* `m`: the number of rows.
+* `n`: the number of columns.
+* `rows`: the array of row indices of nonzero elements.
+* `cols`: the array of column indices of nonzero elements.
+* `vals`: the array of values of nonzero elements.
